Gravity, light and matter are all the same thing vibrating at different speeds. Take a 10 sided polyhedral die and mark each side, X, Y, Z, Time, Gravity, solid, liquid, plasma, gas, light, magnetic memory, 0 and 1. We can see and experience XYZ and the elements. We can not see other sides of this die. But we need to detect them and know what they are in order to master time. We will understand Gravity and time and it's relation to matter at the same time. Gravity and time are connected and distorted in the orbit of a singularity. You have only to circumnavigate a singularity in order to travel time. It is like surfing a wave.
